Recent Tutoring Session Reviews
"In preparation for her upcoming midterm, the student and I spent three hours reviewing various topics in chemistry. For each topic, I spent roughly 10-15 minutes lecturing and explaining the material in depth. These topics included: -Stoichiometry: The branch of chemistry that deals with the relative quantities of reactants and products in chemical reactions. -The Ideal Gas Law (PV=nRT): The equation of state of a hypothetical ideal gas. -Acid and base chemistry: Titrations and identifying acids and bases. -Balancing net ionic equations. -Identifying functional groups within organic molecules. -Identifying reactions in organic chemistry."
"The student has gained understanding of important fundamental concepts (atom structure, for example) and is now applying them to more challenging concepts (ionization, for example). Today we first addressed questions relating to her lab report due tomorrow, involving the periodic table, relative reactivity of elements, and the periodic trends in reactivity. We went over the questions and she felt confident in writing the conclusion on her own. We then focused on two worksheets from class that addressed differences between groups of elements and similarities within groups of elements. In particular, since it had not yet been addressed in class, we discussed the relation between valence electrons, stability, and ions formed within groups."
"The student had taken a test yesterday and wanted to review his test questions. We also discussed how electrons in an atom can shield the nucleus from the valance electrons."
